Dl E FOR THE MANUFACTURE OF LIDS FOR JOURNAL=BOXES.

SPECIFICATION forming part of Letters Patent No. 397,786, dated February12, 1889.

Application filed December 10, 1888. $erial No. 298,155. (No model.)

To all who/1t it may concur/t.-

Be it known that I, NATHAN H. DAVIS, a citizen of the United States,residing in the city and county of Philadelphia, State of Pennsylvania,have invented a new and useful Improvement in Dies for thel\'[anufacture of Lids for Journal-Boxes, which improvement is fully setforth in the following specification and accompanying drawings.

My invention consists of dies for the manufacture of lids for ajournal-box embodying means for forming a lip by which the lid issupported.

It also consists of means for Hanging the opening which receives thepivotal boltof the lid.

Figure 1 represents a top or plan view of the lower die. Fig. 2represents an irregular vertical section in line a: 00, Fig. 1. Fig. 3represents a bottom plan view of the upper die in perspective. Fig. 4represents a section of a portion of the two dies on line 3 y, Fig. 1,on a reduced scale. Fig. 5 represents aview of a portion of a figure,certain parts thereof being in different position. Fig. 6 represents aperspective of a lid on a reduced scale made in accordance with myinvention.

Similar letters and numerals of reference denote corresponding parts inthe several tigures.

Referring to the drawings, A and B represent the upper and lower dies ofa pair of dies for the manufacture of a lid for a journal or box, saidlid consisting, as in Fig. (3, of a body,

1, with a grasping-piece, 9, at one end, a

flanged opening, 3,at the other end to receive the axial bolt or pivotof the lid,alip,- l,above said opening, by which the lid may besupported in horizontal position, and a concavity or socket, 5, toreceive the head or outer end of a journal or axle. Secured to the faceof the upper die, at one end thereof, is a depen ding block or shoulder,0, having a workingface, (3, on the side thereof. Secured to the face ofthe lower die and rising therefrom is a block or shoulder, D, having aworking-face, 7, on the side thereof, said shoulders being at coincidentends of the dies, the :face (3 of the upper die bein adapted to descendand ascend within the face 7 of the lower die, with a space between themequal to or approximately equal to the thickness of the lip l of thelid, as will be seen in Fig. In the lower die is a vertical opening, 8,to receive the flanging punch or die 9, which is secured to the upperdie and has a face somewhat conical. Surrounding the upper portion ofthe punch and shank thereof is a wiper or stripper, 10, which plays inan opening in the upper die and is pressed outward in downward directionby a spring, 11, the diameter of the wiper being greater than that ofthe opening 8, as will be seen in Figs. 4 and 5. On the face of theupper die is a convex projection, 12, and on the face of the lower dieat a coincident place is a concave depression, 13. die are supports andguides 15, which are of the form of pins, located vertically in the dieand adapted to rise and fall, their rising motion being occasioned bysprings 16, suit-ably applied. On the upper ends of the pins areshoulders 17, which face inwardly, it being seen that the blank shown indotted lines, Figs. 1 and 2, is placed on the pins and retained thereonowing to the shoulders 17, the plate being elevated from the face of thelower die. In this position of parts the upper die descends, when thepunch enters an opening in the plate previously made and flanges thewall of said opening, as will be seen in Fig. 4. The wiper 1O enters theopening in upper die, while its lower face is in contact with the metalaround the flanged opening, as in Fig. 4. The concavity and convexity 12and 13 form the socket 5, as also seen in Fig. 4.

The shoulder C bears against the end of the plate near the flangedopening 3 and forces the same downwardly against the lower die, when theface 6 of said shoulder and the face '7 of the shoulder D throw up theadjacent portion of the metal forming the lip 4, as will be seen in Fig.2, it being noticed that the guides 15 are forced into the lower die bythe descending upper die. The upper die now rises, whereby the guides 15are permitted to return to their normal position, thus lifting the platefrom the face of the lower die. As

the upper die rises the spring 11 exerts pressure on the wiper 10, so asto force the same outwardly and downwardly, whereby it strips the wallof the flanged opening from the punch or flanging die. The plate is 110win the form Rising from the lower 2. Dies provided, respectively, withthe opening 8 and punch 9, for forming the flanged opening of the lid,and the Wiper 10, for stripping the plate from said punch, said partsbeing combined substantially as described.
